PITTSFORD — Expanding the sidewalk project from Pleasant Street to Route 7 is under consideration, but town officials want to know how much it will cost before giving the go-ahead.

Town Manager John Haverstock said they are interested in extending the project from the Lothrop Elementary School parking lot — where the sidewalk project is designed to cut off — to Route 7, but need to make sure the cost falls within the budget.

“We want to wait to see what the numbers are from the contractors,” he said, adding they will ask contractors for linear prices to include the extension.

This alternative was presented to the Select Board by project engineer Chrissy Legge with the Dufresne Group on Wednesday.

The new sidewalk will continue from the already existing asphalt sidewalk on Arch Street near the post office building before traveling south toward the intersection with Pleasant Street. A crosswalk will connect both streets before the sidewalk continues to the elementary school parking lot.

Haverstock said the engineers considered changing the location, per request from the state Agency of Transportation, but quickly discarded the proposal. He said it makes sense to leave it on Arch Street because of the existing sidewalk there.

The sidewalk will be 5 feet wide with a 6-inch curve, though Haverstock said they have not determined if they will go with asphalt or concrete. He said it will depend on the cost, and both materials have their downsides and upsides.

“With asphalt it holds better cleanup and maintenance, while concrete, while beautiful, is known to be susceptible to salt,” Haverstock said.

Bids will go out later this year. Construction, though, is not expected to begin until 2014 because of funding procedures the town needs to accomplish beforehand. The project is estimated to cost close to $400,000.

About 80 percent of the project will be paid through two federal transportation grants awarded to the town in 2009 and 2011. The town is expected to pay the rest with at least 10 percent in cash while the rest can be in kind.

The town has budgeted $20,000 a year for the last three years and another $20,000 is budgeted for the upcoming fiscal year.
